F. H. SCHNEIDER OIL BURNING RANGE FOR HEATING AND COOKING 2Sheets-Sheet? Filed Dec. 10, 1934 W T N E V m TTQRN EY Patented July 27,1937 UNITED STATES PATENT OFFICE OIL BURNING RANGE FOR HEATING ANDCOOKING In the design for an oil burning range for heating and cookingmany factors have to be taken into consideration which are not materialin the design of a gas range. Among these factors are the following: Thedischarge flue of the range must be connected withthe chimney to carryoff the waste products of combustion. The flue construction shouldprovide for the passing of the flue gasses directly to the bottom of theoven. A minimum of draft should be used to prevent an excess amount ofheat passing into the discharge flue of the range. An individual burnerassembly should be provided for oven heating and for top cooking andprovision made for also using the oven burner for top cooking.

The walls should be insulated so that the range will be eificient andcomfortable in hot weather.

The doors and coveralls should be arranged so that when open a maximum'of room heating can be obtained in cold weather. Provision for broilingby the radiant ,heat energy of the flame, where it is hottest shouldalso be present.

In my present invention proper consideration has been given to thesefeatures to produce an oil burning range which will be emcient andeconomical for room heating and for cooking.

My invention, therefore comprehends a novel oil burning range, whereinthe heat from the oven burner first heats the bottom of the oven, thenpasses around the sides and top to the discharge flue so that a minimumof draft is required to operate the burner.

It further comprehends a novel construction and arrangement of burners,ovens, and flue passages.

It further comprehends novel means to enable one to use the radiant heatenergy of the flame for broiling.

Other novel features of construction and advantage will hereinafterappear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in theaccompanying drawings typical embodiments of it, which, in practice,will give satisfactory and reliable results. It is,

however, to be understood that the various instrumentalities of which myinvention consists can be variously arranged and organized and myinvention is not limited to the exact arrangement and organization ofthese instrumentalities as herein set forth.

Referring to the d'rawings:

l designatesan oil burning range for heating and cooking embodying myinvention. The body portion 2 of the range consists of double walls withinsulation between them forming the bot- 10 tom and side walls, whichlatter carry a cast iron top plate 3 for top cooking. The top plate hasa desired number of pot receiving openings I 4 and covers 5. 6designates insulated coveralls hinged at their rear ends as at 1, seeFigures 3 and 4. The coveralls can be raised against a balustrade 8.

The range is provided with an upper burner chamber 9 in which is locatedan upper oil burner III for top cooking, and with a lower 20 burnerchamber ll provided with a lower oil burner l2. These burner chambersare separated from each other by an insulated wall I3. As illustrated,the range is provided with superimposed ovens l4 and IS, the upper ofwhich forms 25 a baking oven, and the lower of which forms a warming orbroiling oven. An insulated wall l6 of the broiling oven forms asidewall of the lower burner chamber and merges into an upwardlyinclined insulated top wall l'l which ex- 30 tends tothe rear wall ofthe range and is spaced from the bottom wall of the baking oven to forma bottom flue- 18 which leads from the lower burner chamber H above itsburner [2. This flue l8 merges into an upwardly extending flue 35 I9between the sidewall of the range and the side wall of the'baking ovenand merges into a laterally extending top flue 20 between the oven topand the top of the baking oven so that the top will be heated by heatfrom the lower burner. 40 A baffle 2| causes the products of combustionto pass in the direction of the arrows seen in Figure5 to the dischargeflue opening 22 leading to the discharge flue 23. The exit pipe 24 leadsto the chimney and isprovided witha 45 damper 25. A baffle 58 extendsfrom the front wall to the rear wall, see Figure 5, to prevent heat fromthe upper burner passing to the top flue 20.

The top of the baking oven I4 is extended downwardly to form a side wallof the upper burner chamber spaced from the juxtaposed side wall of thebaking oven forming a heating space 26 which if desired may open asshown into the flue 18 but is closed at its top.

The bottom of the baking oven is preferably insulated as at 21.

The front wall of the range 28 is preferably of cast iron and has hingedto it an insulated door 29 for the upper burner chamber 9, an insulateddoor 30 for the lower burner chamber ll, an insulated oven door 3| forthe baking oven l4, and an insulated door 32 for the broiling oven [5.

The top wall I! of the broiling oven I5 has an opening 33 leading fromthe flue l8 and guides 34 are provided for an apertured plate 35 whichis removable for cleaning.

When the broiling oven is not used an insulated cover 58 may be placedin the opening 33.

The side wall of the burner chamber is provided with observation windows36 and 31. 38 designates the oil reservoir having a line 39 leading tothe upper burner and provided with an oil level float valve 40. A line4| from the oil reservoir to the lower burner is provided with an oillevel float valve 42. The upper bunier chamber has an air intake 43 andthe lower burner chamber has an air intake 44.

Each oil burner is of the same construction and has an adjusting valve45 and a lighting device 45.

Air intakes 41 and 48 are provided.

The range is mounted on legs 49 having any conventional levellingdevices 50.

5| is a heat reflecting bafile for the upper burner having an opening 52for lighting the burner. 53 is a heat reflecting baflie for the lowerburner having an opening 54 for lighting the burner. 7

The oil burner for heating the baking oven can have any desired locationso long as the heat is passed directly to the bottom of the oven toprovide an even distribution of heat.

In Figure '7, the lower burner forthe baking oven is positioned directlybeneath the baking oven so that the products of combustion impingeagainst the insulated bottom of the baking oven which is of uniformthickness as at 55 instead of tapering in the.direction of flow of theflue gasses so that in both cases there is a uniform distribution ofheat over the bottom of the oven. An insulated wall 55 contributes toform a warming chamber 51.

If desired a hot water coil 59 may surround the top burner.

In order to increase the heating capacity of the range, I may employpipes 60 having any desired arrangement in the upper burner chamber.Cold air enters at the bottom, and the upper ends of the pipes terminateat a recess 6| in the top. The upper ends of the pipes may be controlledin any desired manner and for purpose of illustration I have shown aremovable cover 62, flush with the range top.

The oil burners are of conventional construction and can be purchased inthe open market. For convenience of illustration I have shown one upperand one lower oil burner but it is to be understood that each burnerassembly may consist of one ormore burners.

Due to the flue arrangement, a minimum of draft is required to operatethe oil burners, as the products of combustion from the lower burnerpasses directly beneath the baking oven and the heat does nothave to bedrawn downwardly towards'thebottom of the oven but has an upward travel:

The burner can be adjusted and lightedfrom the front of the range byopening the burner doors.

One or both of the coveralls can be closed when using the baking oven.

When used for room heating, the radiant heating energy from eitherburner can be utilized by opening the burner doors, and for additionalheating the coveralls can be raised and the oven doors can be opened sothat a maximum of room heating can be economically obtained.

It will now be apparent that I have devised a new and useful oil burningrange for heating and cooking which embodies the features of advantageenumerated as desirable in the statement of the invention and the abovedescription, and while I have, in the present instance, shown anddescribed preferred embodiments thereof which will give in practicesatisfactory and reliable results, it is to be understood that theseembodiments are susceptible of modification in various particularswithout departing from the spirit or scope of the invention orsacrificing any of its advantages.
